Problems solved by technology

However, due to many reasons, such as regulations, law enforcement, and national security, legal interception of voice communication is required for wide area voice communication.
In practical, it is very difficult to intercept all possible routing paths between one end and another end.

Abstract

The present invention provides a communication system, which comprising a plurality of user agents, a media relay gateway, a command center, and a session controller. Each user agent is capable of exchanging media stream with another user agent. The media relay gateway is used for receiving and forwarding media stream among said plurality of user agents. Moreover, the command center is used for receiving forwarded media stream from the media relay gateway. And the session controller re-directs and associate exchanged media streams between the plurality of user agents to said media relay gateway according to a monitor command of said command center.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to Internet Protocol voice communication, and more particularly to Internet Protocol voice logger. [0003] 2. Description of the Prior Art [0004] Packet switch voice communication is getting more and more popular in this Internet age. However, due to many reasons, such as regulations, law enforcement, and national security, legal interception of voice communication is required for wide area voice communication. [0005] Conventionally, it is required to have a top application layer processing mechanism to filter, monitor, and / or record voice stream through the backbone or trunk communication wires. Normally the legal interception requires heavy burden on the central packet switches and / or routers since all packets have to be parsed and compared with a list of filter, monitor, and / or record conditions. When one more condition is added into the list, there would be one more compari...
